I dont know about you, but I'd rather not wait an extra 30-60 seconds for my second derivative to come up or graph when I can get it faster. It certainly helps on exams (eg. AP -- inwhich test timing is brutally enforced). I also *think* the TI-89 has a faster processor and for quite some time, but just didn't have a usb input.
